摘要：
DC magnetic susceptibility measurements of the magnetoplumbite-like compound SrCr//8Ga//4O//1//9 show that no magnetic phase transition occurs up to T equals 4. 2K in spite of high antiferromagnetic interactions making apparent a high degree of magnetic frustration (O/Tg 117). The determination of a preferential sublattice cation distribution by neutron diffraction allows us to interpret this effect as associated with an effective decrease of the lattice dimensionality.
